I added the performance vs. benchmark in the Fundsmith thread
Fundsmith focuses on large caps, Smithson focuses on small - mid caps which should in theory produce higher returns over the long term but with more volatility. The fund is closed ended to limit it’s size and was created partly due to Fundsmith growing so large it could no longer invest in mid size companies. Dominos Pizza was quoted as one example. I am gradually opening a position in Smithson via DCA, I am proceeding with some caution since SSON only has a 3 year track record.
